AquaVene TPEE by Kae Hwa Industrial offers a non-porous waterproof breathable film made from thermoplastic polyester elastomer, delivering elasticity, heat resistance, and vapor-permeable comfort for outdoor and textile applications.
Thermoplastic Polyester Breathable Film
AquaVene TPEE, developed by Kae Hwa Industrial is a high-performance thermoplastic polyester elastomer (TPEE) breathable film engineered for durable waterproof and moisture-vapor transmission.
Through a monolithic, non-porous structure, it provides a seamless waterproof barrier while allowing moisture vapor to diffuse through its hydrophilic polymer matrix — ensuring long-lasting comfort, flexibility, and protection.
This film combines excellent elasticity, thermal resistance, and mechanical strength, making it ideal for textile lamination, outdoor apparel, footwear, and technical applications requiring consistent performance under stress, washing, or extreme environments.
The AquaVene™ TPEE membrane leverages advanced thermoplastic polyester elastomer chemistry to deliver an exceptional balance of mechanical stretch and durable barrier safety. Unlike traditional microporous films that rely on physical air channels prone to contamination or clogging from body oils, this monolithic, non-porous structure facilitates breathability entirely via solid-state molecular diffusion. The segmented polyether-ester block copolymers within the matrix absorb internal moisture vapor at the molecular level, transferring it efficiently through the dense polymer chains while maintaining an absolute, uninterrupted shield against external wind, heavy rain, and fluid contaminants.
In the high-performance outerwear and sportswear sectors, polyester-based fabrics represent the global volume standard for windproof and waterproof shells due to their versatile performance. AquaVene™ TPEE provides apparel designers with the critical link to close the loop in circular product design. By bonding polyester face fabrics with our chemistry-matched TPEE membrane, manufacturers can engineer a unified, 100% Polyester mono-material laminate system. This eliminates the costly and labor-intensive stripping or material-separation processes typically required at a garment's end-of-life, allowing the final laminated textile composite to be shredded, re-granulated, and fully upcycled into high-value polymer streams.
Beyond consumer apparel, AquaVene™ TPEE stands as an elite engineering standard for high-end medical protection. Because it forms a completely non-porous, solid-state polymer shield, it provides an absolute fluid and biological barrier capable of meeting stringent international standards, such as AAMI Level 4. It effectively blocks the penetration of blood-borne pathogens, aggressive viruses, bacteria, and liquid chemical splashes, ensuring maximum security for surgical environments and critical care units. Furthermore, the robust thermal backbone of the TPEE matrix exhibits superior resilience against heat and moisture fatigue, allowing laminated medical gowns to undergo repetitive autoclave sterilization (high-temperature steam cleaning) without losing its waterproof integrity or vapor permeability—making it the ultimate solution for durable, reusable medical protective fabrics.
Built for harsh alpine environments and aggressive industrial converting, AquaVene™ TPEE exhibits outstanding thermal stability, flexible low-temperature resistance, and elite elastic recovery without the use of toxic additives. It is inherently fluorine-free (PFC-free), providing global brands with a premium sustainable alternative that aligns with strict chemical regulations without sacrificing technical integrity. Furthermore, the dense crystalline backbone of the TPEE matrix is highly resilient against mechanical fatigue, showing excellent dimensional stability and delamination resistance even after repetitive industrial washing cycles, severe structural flexing, and prolonged high-tension roll-to-roll processing.

AquaVene™ TPEE is a halogen-free, non-porous monolithic membrane that is entirely PFAS-free and PFC-free, ensuring it complies with the strictest global environmental regulations. Unlike standard PTFE membranes, TPEE is fully recyclable and does not release toxic byproducts during its lifecycle, making it the ideal sustainable choice for premium consumer and industrial applications.
AquaVene™ utilizes advanced monolithic (non-porous) technology. Breathability is achieved at a molecular level through hydrophilic molecular chains that actively absorb and transport moisture vapor away from the body or package. Because there are no physical pores, the film acts as an absolute solid barrier against liquids, bloodborne pathogens, viruses, and wind, maintaining consistent performance even when stretched or soiled.
Yes. As a thermoplastic polyester elastomer, AquaVene™ possesses excellent thermal stability. It maintains its structural integrity and performance at elevated temperatures, making it highly compatible with various thermal lamination processes, hot-melt adhesive applications, and industrial sterilization methods (such as autoclaving or gamma radiation) required for medical applications.
Not at all. AquaVene™ inherently combines high elasticity with exceptional tensile strength. Unlike microporous films where stretching can distort the pores and compromise waterproof integrity, our monolithic TPEE structure retains its uniform moisture vapor transmission rate (MVTR) and high water column resistance even under repeated dynamic stress and stretching.
AquaVene™ is highly versatile due to its premium barrier properties and eco-friendly nature. It is widely used in:
Premium Outdoor & Activewear: For high-performance windproof and waterproof jackets.
Medical & Healthcare: For AAMI Level 4 surgical gowns, drapes, and protective apparel requiring total fluid and viral barriers.
Industrial Packaging & Automotive: For specialized protective covers and desiccants requiring controlled moisture control and high durability.
